IMPROVEMENT IN WATER-CLOSETS.

Specification forming part of Letters Patent No. 203,045, dated April 30, 1578; application filed April 15, 1878.

To all whom it may concern:

Be it known that I, MATTHEW HOGAN, of Hartford, in the county of Hartford and State I of Connecticut, have invented certain new and useful Improvements pertaining to a Water- Fig. 3 is a detached vertical sectional view of the trap in the waste-pipe leading from the overflow-receiver which surrounds the basin. Fig. 4 is an end view, and Fig. 5 is a view in central longitudinal section, of the faucet or cook which supplies the tank.

The letter a denotes the bowl or receivingbasin of a water-closet; b, a water-way leading therefrom to the stand-pipe c.

The letter d denotes a short pipe or collar rising from the top of the trap e, on which fits and fastens, by screwing or otherwise, the stand-pipe c. The collar (1 contains an internal annular flange, f, pierced by orifices g for the reception of the teats h projecting downward] y from the valve-seat i. This valve-seat is preferably of non corrosive metal, and by tllie arrangement described is readily remova b e.

The valve, as a whole, I will designate by the letter A. Its component parts I will describe hereinafter. The valve A is operated by means of the valve-rod j, which extends up through the slab or seat k, and through the cap I. The top of the stand-pipe c is furnished with the ears m, pierced for the passage of the bolt-rods a, which, coming down from the cap through the slab k and through the ears m, have nuts underneath the ears, and these nuts, when screwed up against the ears, serve to connect the cap I and stand-pipe c to the slab k. These bolt-rods 41., instead of coming down rigidly from the cap l, are hung on traverseloops 0, attached to the under side of the cap I. This arrangement is for the purpose of allowing the bolt-rods to fit to the position of the holes which are drilled in the slab for their passage. When these bolt-rods are rigid on the cap 1, it not unfrequently happens that the holes for their passage through the slab are wrongly drilled, and trouble results.

The trap c has an outlet-valve as well as an inlet-valve. The letter 1) denotes the seat thereof, and r thevalve, which is j ointed to the valverod 8, and preferably is weighted on one side by the weight t. This outlet-valve is located in the stand-pipe a, which is located on top of the trap e. The valve-rod s has up-and-down play in the guide-tube c, which is held fast in the cap to of the stand-pipe u. The letter z denotes the outlet from the stand-pipe u.

The bowl or basin a is surrounded by the overflow-receiver a, to receive accidental overflow. This receiver is provided with the wastepipe I), leading to the main waste-pipe z. This,

waste-pipe b is furnished with a trap, c, having an outlet-valve, (1', closing against backward pressure, as does the main outlet-valve r.

I will now describe the main valve A. The letter 0' denotes the barrel or body thereof, furnished at the top with the returnflange f, dipping into the cup-flange 9, attached to the interior of the stand-pipe c.

When the water-closet is quiet the water stands about as represented by the dotted line y, and when the valve A is raised it is never raised so far that the flange f leaves the water, so that the trap formed by the flanges f g is always sealed, whether the valve A be open or closed. Within the barrel 6', and supported from it by supports h, is the cup-flange i. The top of the barrel e bears at the top the return'flangej, dipping into the cup-flange i. If, bymischance, the water rises too high in the bowl on, it flows up over the top of the valve A, thence down into the cup i, and escapes over its edge down below.

It will be observed that the flanges t j form a trap. But the valve A is furnished with still another trap, which closes by backward pressure, the same as the valves 7' d, so that the whole device is protected by positive valves against the pressure of sewer-gases, 850. The water coming from the cup z" falls down into the chamber k, whence it must pass out through the trap Z furnished with the valve m, which closes against back pressure of gases. This trap Z is contained within the casing 12,

. which water is fed to the closet from an open tank, which tank, by my method, can be 10- cated at a distance from the closet or in another room. The letter 0 denotes the open tank; 19, the supplyrpipe leading therefrom to the bowl a r, the valve opening into the supply-pipe depending from the lever s, from which the pull-wire t runs to the float-valve u contained in the pipe or reservoir Q7, which, by pipe to, communicates with the stand-pipe 0, so that the water in pipe U' stands at the same height that it does in the bowl a and stand-pipe c. When the closet is at rest the height of the water in pipe '0 is such as to cause the valver toremain closed; but when the main valve A is opened the float u will fall with the fall of the Water, and open the valve 4", and send a fresh supply of water to the bowl a; When themain valve A is dropped to its seat the water will gradually rise in pipe '0, and so close the valve r. This gradual rise of the float u gives the requisite afterwash in the bowl to.

I will now describe the'fancet or cock which supplies the tank 0. The letter a denotes the body or barrel of the faucet; I), the valveseat screwing into the body a; c, the valverod bearing the valve (1, which in closing moves against the current of inflowing water. On the rotary shaft 0 is a double cam, f, acting in some positions to close the valve, and in others to allow it to open. The ball (a float) g on the arm h, attached to the outer end of the shaft ei, gives the requisite movements' to the shaft. The head or inner endz' of the valve-rod screws upon the valve-rod, so that as the cam f or this head wears away by use this head can be adjusted to compensate for such wear.

I claim as my invention 1. The pipe d, provided with the perforated flange f, in combination with the valve-seat 5, provided with the teats h.

2. The trap e, in combination with the valve r, pivoted to the valve-rod s.

3. The cap Z, provided with the traverseloops 0, in combination with the bolt-rods n.

4. In combination, the overflow-receiver a, waste-pipe b, and trap 0, provided with the valve d. o

5. In combination, the pipe 0, provided with the cup-flange g, the valve-barrel 6, provided with the return-flanges fj, and the cup '5'.

6. In combination, the valve A and the valved trap Z contained in or carried on the valve A 7. In combination, the basin a, stand-pipe a, valve A, open tank 0, supply-pipe p, valve r, lever 8, rod t, float u, pipe 2:, and pipe 20.

8. In combination, the barrel of faucet a, v

the valve-seat b, the valve-rod 0", provided with the valve d, and the shaft e provided with the cam f. r I

9. In combination, the faucetbarrel a, valve-seat b", valve-rod 0, provided with the valve d" and adjustable head i, and the shaft 6, provided with the cam f.
